I think I've got something new here for the database. Spotted these in the recycling bin at work and thought I would test them out. One needed a trickle charge but the tested out at 2555, 2679, and 2712

Specs are available on the website:http://www.efestpower.com/index.php?ac=article&at=read&did=396

Model: IMR18650

Rated capacity: 3000mAh
Nominal Voltage: 3.7V
Voltage cut-off: 2.5V
Max Charging Current: 4A
Standard Charge: 2A
Discharging Current: 20A
Plus Discharging Current (their words not mine): 35A
Charging Temperature Range: 0 - 45C
Discharging Temperature Range: -20 75C

Hi Guys,

Im inneed of help with an Hoverboard Battery, does anyone know these cells?Are they high capacity charging/discharging?

I want to replace his36V battery 10S2P,image_evgxvt.jpg

New user here, signed up to post this apparently new battery for the database. Picked this up from a recycle yard and googling the numbers returned no info. There were 6 batteries in the pack. Here are pics and the text from the battery.

Got a couple,

First one is a total mystery. Pulled from a pack like this.

image_vgofru.jpg

image_xkqxnt.jpg

According to the pack its11.1V at 8800mAh makes sense for all the cells to be 2200mAh.
Well I tested these with 4 different testers and they come up every time at least at 2500mAh and up.

image_hcdblt.jpg

No markings at all on the gray wrapper even with a searchlight and microscope.

image_efizdu.jpg

image_cwaadc.jpg

Decided to unwrap one and there were these markings and that's it.

image_qdwjvx.jpg


The other one I could not find in the cell database or anywhere else for a matter of fact.
It is self explanatory as far as mAh is concerned but no other specs.
on the SkyRC M3000 the are showing ~2150mAh so not a bad cell.

Just got over a cell that seems to miss in the database.


I found a webpage with specshere:https://www.dnatechindia.com/LG-MJ1-18650-3500-mah-Li-ion-battery-india.html

Hey, I found one of the same brand/logo, different number of sides on the top cap, no discernible model number (no luck on finding data either):

image_odiyyr.jpg


image_wjmiuc.jpg


image_oriihp.jpg


And here's a Samsung ICR18650-24B, which appears to be a variant of the 24A/24E that are already in the database. No datasheet that I could find, but there's data on it at Voltaplex and here:https://voltaplex.com/samsung-24b-18650-battery-icr18650-24bhttps://merkandi.us/archive/battery-li-ion-18650-samsung-icr18650-24b-3-7v-2400mah/256007which claims 2400mAH capacity, 3.7V, 800mA standard charge, 960mA "rapid charge",2.4A max charge, 4.8A max discharge.

This is likely a Sanyo UR18650A:https://secondlifestorage.com/t-Sanyo-UR18650A-Cell-Specificationscheck the side for a faint imprinted model number.

Vape cells like this are usually rewraps of major manufacturer cells. This one for example looks very similar to an LG HG2 (same top cap shape/sides, very similar voltage curve shape:

Generic 2AH cell to add, closest I can find on spec/appearance is the following cell from Greenway battery:
https://www.globalsources.com/gsol/I/Lithium-ion-battery/p/sm/1169141944.htm#1169141944https://www.alibaba.com/product-det...?spm=a2700.7724838.2017115.193.77d072f753Wbmjhttps://www.greenway-battery.com/product/Battery-Cell-30.html
18650E-0200Spec states 2.2AH typical capacity, 4.4A max discharge rate.


image_ceuiiu.jpg


image_ghmuco.jpg


image_wbrysa.jpg


And here's a generic 3200mAH cell I bought from eBay. Thought it would be fake but turns out to be real (or at least close to spec, 2963mAH tested in a Miboxer C2 4000 at 1.5A):


image_fmroqj.jpg


image_aoszbg.jpg


image_sviuey.jpg


Again hard to find sources but I believe it is a DLG cell, INR18650-320:https://www.alibaba.com/product-det...spm=a2700.7724857.normalList.7.61cb6806abg0h7https://www.alibaba.com/product-det...pm=a2700.7724857.normalList.58.61cb6806abg0h7https://www.alibaba.com/product-det...pm=a2700.7724857.normalList.68.61cb6806abg0h7
Spec states 3.1AH minimum, 3.2AH typical, 3.2A max charge current, 6.4A max discharge current (to 2.5V), <40mOhms IR.

It appears to come in a blue wrap with no other markings/barcodes also:

Another mystery generic cell from a generic 6-cell laptop pack:


image_ljpsaq.jpg


image_hljtga.jpg


image_qqwzxt.jpg


Capacity tested 584mAH/181mOhm and 558mAH/163mOhm, so not sure what the original capacity was since this must be very heavily ddegraded. I'll update if I ever find the cell info, but after a quick search of the model number(s) (FC14-HE-L097) on Google and Alibaba, no hits.

I guess i was not allowed to add pictures to the cell database so ill post here I have some LGDDBHE21865 they are 2500mah and came from a ryobi 40v 5Ah

Note: We need pictures to create a database entry. You can upload them where it says "Drop files here to upload" in the full post editor or new thread editor.

Found a cell I could not find in the database. The green one listed for ICR18650NH does not match.

Unknown brand from a laptop. Capacity rated in Wh which is unusual.
